METHOD AND INSTALLATION FOR SEPARATING A MIXTURE OF HYDROGEN AND CARBON MONOXIDE

摘要

The invention relates to a method for simultaneously producing hydrogen and carbon monoxide, whereby the synthesis gas is subjected to decarbonatation in a decarbonatation unit (2), and to desiccation in a desiccation unit (5). The remaining constituents are cryogenically separated and a hydrogen-enriched gas (7, 19, 21) is recycled upstream from the decarbonatation unit and downstream from a unit for producing synthesis gas (F).
